7.2 Installing the refrigerator draught-proof
Gas powered cooling devices in caravans and motorhomes must be installed
draught-proof according to EN 1949. This means that the combustion air
won't be taken from the interior room and that the exhaust gases are
prevented from direct entry to the living space.
A suitable sealing between the backside of the refrigerator and the interior of
the vehicle must be provided.
!
WARNING! Fire hazards!
Do not use easily inflammable materials such as silicone
sealants, installation foam, etc. for the draught-proof installation.
The manufacturer recommends using a flexible seal to simplify the assembly
and disassembly for maintenance.
➤ Fix the lip seals (fig. 4 1, page 3) to a stop bar behind the refrigerator,
e.g. by gluing.
➤ While mounting push the refrigerator against the stop bar with the lip
seals. Thereby the area behind the device is sealed towards the interior
of the vehicle.
7.3 Making air inlet and vent hole
I
NOTE
At high ambient temperatures the refrigerator can only generate
its maximum cooling capacity if a optimal ventilation and
de-aeration is provided.
➤ Produce an air inlet and a vent hole in the outer wall. Observe the follow-
ing instructions, see chapter "Preparing the installation" on page 14.
If the air inlet's ventilation grid cannot be mounted flush to the floor of the fit-
ted niche, you must install an air inlet in the floor:
➤ Make a vent opening of a diameter of at least 40 mm on the ground be-
hind the refrigerator in the area of the gas burner (fig. 5 1, page 4). The
vent pipe must be routed directly to the outside. So leaking unburnt gas
can escape to the outside.
➤ Shield the end of the opening with a deflector to prevent it from mud or dirt
while driving (fig. 6, page 4).
